> I'd safely assume that any X11 GUI app that fork'ed then executed GUI calls would suffer from undefined behaviour. Apart from anything else, it'd be sharing an X11 connection with it's parent process, so there would be all sorts of concurrency issues.

Fortunately, you are wrong. The X11 protocol allows the child to open its own display and create its own graphic context without interfering with the parent process.

How many applications out there actually take advantage of that ability? I'm fairly certain that sort of exotic thing isn't ever used by either GTK or Qt. X11 has a lot of flexibility that seems to never actually get used for one reason or another.
